DETAILED DESCRIPTION OF EMBODIMENTS

FIGS. 1 to 5B show an infant seat according to an example of the presentdisclosure and generally designated 130.

The infant seat 130 comprises a support member 132 configured as aU-like shaped frame with an interconnecting bar 134. In the illustratedexample the support member 132 is in the form of a rigid, light-weightframe. It is however appreciated that other forms can be configured,either as platforms (surfaces) or otherwise shaped frames.

A rigid bearing frame 138, configured as a U-like shaped frame, ispivotally articulated at one end thereof to the support member 132,through a pivot link 142 disposed at each end of the respective ends ofthe bearing frame 138 and the support member 132. The pivot links 142are connected by a connecting rod 133 (FIG. 9A), which is fitted with afirst locking mechanism 144.

The first locking mechanism 144 comprises a handle 135 such that itsactivation is performed by a single action, i.e. by pressing the handle135.

The first locking mechanism 144 facilitates arresting the bearing frame138 at a varying first angle α, whereby the bearing frame 138 can bemanipulated between collapsed position, extending parallel or near toparallel to the support member 132, defined by angle α₁ (FIGS. 1A and1B) and at least two operative positions, namely a bouncing position,defined by angle α₂ (FIGS. 2A and 2B) and one or more high positionsdefined by angle α₃, such as a reclined high position (FIGS. 3A and 3B)and an inclined high position (4A and 4B), wherein α₁<α₂<α₃.

A rigid seat frame 150 is pivotally articulated at 154 to a second,opposite end, of the bearing frame 138, said seat frame 150 isconfigured with a seat 156, said seat being a seating member designedand shaped for comfortable accommodating an infant seated therein.Appropriate harnessing 158, buckles, etc., may be provided, e.g., forsafety of the infant. A second angle β extends between seat frame 150and the support member 132.

According to a further example, not illustrated, the support member canbe configured with arched arms or with a convex dome, such that theinfant seat can rock thereover. Vibrating can be prevented by provisionof arresting members configured for canceling the arched vibratingsurface and sturdily engaging a ground surface.

It is appreciated that a seating member is desired for its manyadvantages, including, among others, its light weight, being easilyfoldable, ventilating properties, detachable for purpose of washing,replaceable, etc. However, it is appreciated that other seat forms arepossible (not shown).

According to some examples, the seat frame 150 is further supported overthe bearing frame 138 by a seat support, which in the present example isin the form of a pair of a support frame assembly generally designated157, extending between the seat frame 150 and the bearing frame 138. Ascan be seen in detail in FIGS. 6A to 6D, the support frame 157 comprisesa seat bracket 159 pivotally articulated to the seat frame 150 by rods161 at pivot joints 163 (FIGS. 1A to 4B), and a bearing bracket 165(FIGS. 6A to 6D) pivotally and swingable articulated to the bearingframe 138 through coupler unit 167.

Whilst seat bracket 159 pivotally articulated to the seat frame 150,bearing bracket 165 can be pivotally and swingable articulated to thebearing frame 138. Thus, bearing bracket 165 can be lockingly arrestedat two distinct pivotal positions as will be discussed hereinafter.

The bearing bracket 165 is configured with a female locking member inthe form of socket 171 and the seat bracket 159 is configured with acorresponding male locking member in the form of a plunger portion 177configured for snug locking engagement within socket 171 (FIGS. 6B and6C). It is noted that the seat bracket 159 comprises a resilient pressknob 179 configured for locking within corresponding locking window 181of the bearing bracket 165, wherein disengagement from one another isfacilitated by depressing the press knob 179 and pulling the plungerportion 177 out of the socket 171 (arrow 181 in FIG. 6C).

Also noted, the infant seat 130 can assume an operative positionsuitable for accommodating an infant, only when the support frame 157 isassembled and locked. Accordingly, an attempt to erect the infant seat130 whilst the support frame 157 is disconnected (FIG. 6D) is notpossible since the bearing bracket 165 is disposed upside down, i.e.with the socket 171 facing away from the plunger 177. Yet, an attempt toerect the infant seat with the support frame 157 not completelyassembled and locked (FIG. 6C) will result in spontaneous lockingthereof, i.e. sliding displacement of plunger 177 in direction of arrow183 (FIG. 6C), into the locked position (FIG. 6A).

With further reference to FIGS. 7A and 7B, and as already mentioned,bracket 165 is also swingable, whereby axle 191 is supported to couplerjoint 167. Axle 191 is configured at its respective ends with a swingarm portion 211, pivotally secured to the coupler joints 167 anddisplaceable between a first position (FIG. 7A), and a second position(FIG. 7B), corresponding with the first, reclined, high position (FIGS.3A and 3B), and the second, inclined, high position (FIGS. 4A and 4B).

A second locking mechanism 160 is configured at the support frame 157over axle 191, for arresting thereof and preventing spontaneousdisplacement of the support frame 157, whereby manipulating thereofbetween the first reclined high position and the second inclined highposition can be facilitated upon unlocking the second locking mechanism160.

It is thus appreciated that swinging displacement of the axle 191between its distinct positions (FIGS. 7A and 7B) determines theinclination of the seat frame 150 with respect to the bearing frame 138,i.e. determine the second angle β.

In the illustrated example, the seat frame 150 is pivotally displaceablebetween a collapsed position (FIGS. 1A and 1B), defined by angle β₁wherein the seat frame 150 is flush or substantially parallel withrespect to the bearing frame 138, and two distinct inclined positions,namely a reclined high position, defined by angle β₂ (FIGS. 7A and 7B),and an inclined high position, defined by angle β₃ (FIGS. 4A and 4B),wherein β₁<β₂<β₃. It is seen that in the particular example, at thebouncing position (FIGS. 1A and 1B) the angle β is similar to angle β₂of the reclined high position, (FIGS. 3A and 3B).

A bouncing mechanism according to the present example comprises abouncing frame assembly 166 (best seen in FIG. 9A), articulated at arear portion of the bearing frame 138 and configured for bearing at onlya bouncing position, over the support frame 132. The arrangement is suchthat the bouncing mechanism is functional only when the seat 130 is atits bouncing position (FIGS. 2A and 2B), and is dysfunctional at eitherits high positions (FIGS. 3A, 3B, 4A and 4B), as the bouncing frame isdisengaged from the support frame 132. Thus, at the bouncing position,the bouncing frame 166 comes to bear over the support member 32, thusfacilitating bouncing of the seat 130. However, when the bouncing frame166 is disengaged from the support frame 132 (at either its highpositions), the seat will not bounce.

It should be appreciated that the bouncing assembly can be similar tothe bouncing assembly 166 described above or can be any otherarrangement, constituting a part of, or articulated to, the bearingframe 138, or the support member 132.

The infant seat 130 of the present disclosure is manipulable between itspositions, as follows:

A collapsed position (FIGS. 1A and 1B)—at this position the infant seat130 is flattened so as to consume minimal space, rendering it suitablefor storage/stowing/carrying. This is substantially a non-operativeposition, i.e. not suitable for seating an infant;

A bouncing position (FIGS. 2A and 2B)—at this position the infant seatis at a first operative position, which is useful for seating an infantand also soothing, owing to bouncing of the seat. Displacing the seatfrom the collapsed position into the bouncing position takes place byunlocking the locking mechanism 144 and pulling the seat frame 150upwards (in direction of arrow 170 in FIG. 1A) whereby seat frame 150pivots to assume angle β₂ with respect to bearing frame 138 and thelater pivots to assume angle β₂ with respect to the support member 132,so that the bouncing pistons 166 bear over the support frame 132. Then,the support frame 157 should be assembled and locked as discussedhereinbefore in connection with FIGS. 10A to 10D. Once set into thebouncing position, the seat frame 150 and the bearing frame 138 willretain their positions as the locking mechanism 144 at the pivot links142 and the support frame 157 are locked.

A first high position (FIGS. 3A and 3B)—this is a so-called reclinedhigh position. Unlocking the locking mechanism 144 and further pullingthe seat frame 150 upwards, in direction of arrow 174 (FIG. 3A) entailsfurther angular disposition of the bearing frame 138 with respect to thesupport member 132, thus obtaining angle α₃. However, the bearing frame138 remains locked and the axle 191 is at its first position (FIG. 7A),whereby angle β₂ remains. This results in tilting of the seat frame 150into a reclined, almost horizontal position. It is appreciated that atthis position the bouncing frame 166 is disengaged from the supportframe 132, so that the bouncing mechanism becomes inactive.

A second high position (FIGS. 4A and 4B)—this is a so-called inclinedhigh position. Manipulating the infant seat 130 into this position takesplace by unlocking the second locking mechanism 160 and swinging/tiltingthe axle 191 with the support frame 157 articulated thereto upwards, indirection of arrow 176 (FIG. 7A), resulting in an increased angle β₃between the seat frame 150 and the bearing frame 138, and howeverwithout altering angle α₃ between the bearing frame 138 and the supportmember 132. At this position the seat obtains a somewhat inclinedposition, resembling a high seat. Also at this position the bouncingpistons 166 is disengaged, so that the bouncing mechanism becomesinactive.

It should be appreciated that the above arrangement allows a completeseparation between the mechanism which is responsible for manipulatingbetween the first high position and the second high position, i.e.increasing angle β from β₂ to β₃, and the mechanism responsible formanipulating the angle α. Thus, in such arrangement it is prevented froma user to unintentionally manipulate the seat to a second high position,while activating the locking mechanism 144.

Also, the above arrangement is such that the seat cannot be manipulatedfrom the second high position to the bouncing position without passingfirst through the first high position, and similarly cannot bemanipulated from the bouncing position directly to the second highposition.

Collapsing the infant seat from any of its erect, operative positionsinto a previous state requires unlocking both the first lockingmechanisms 160 and detaching the support frame, namely detaching seatbracket 159 from the bearing bracket 165.

According to a particular configuration of the disclosure, the firstlocking mechanism 144 and the second, sliding locking mechanism 160, arenormally disposed at their locked position and will momentarily unlockupon manipulation thereof. According to yet a particular example, thelocking mechanisms can be configured for simultaneous unlocking, e.g. byBowden cables, etc.

It should be appreciated that in the collapsed position the firstlocking mechanism 144 and the second, sliding locking mechanism 160 donot have to be normally locked. The first locking mechanism 144 and thesecond, sliding locking mechanism 160 can be configured with means forlocking thereof in the collapsed position of the seat. Alternatively,the infant seat 130 can comprise one or more additional lockingmechanisms configured for locking the first locking mechanism 144 and/orthe second, sliding locking mechanism 160 in the collapsed position ofthe seat.

The infant seat 130 is further configured with an electronic vibratingmechanism 180 (FIGS. 1A and 2B), which in the present configuration ispart of the pivot support between the seat frame 150 and the bearingframe 138. The vibrating mechanism can be configured with an electroniccircuitry comprising a timer, a vibrating pattern selector, amusic/sound processor etc.

According a modification, the infant seat 130 is provided with amechanism disposed at 154 (i.e., adjacent one or both ends of the seatframe 150 and the bearing frame 138) configured to support the seatframe 150 over the bearing frame 138, thus obviating the need for, andallowing the infant seat to be provided without, a seat support 157 suchas described above and illustrated, e.g., in FIGS. 1A through 4B.

As illustrated in FIG. 8, the mechanism may be disposed within a housing200 which holds therein an end of one of the seat frame 150 and thebearing frame 138 (the mechanism will be described herein with referenceto the housing holding therein an end of the seat frame; it will beappreciated that the infant seat 130 may be provided wherein the housingholds therein an end of the bearing frame without departing from thescope of the presently disclosed subject matter, mutatis mutandis).

As illustrated in FIGS. 8B (in which the cover 200 is removed) and 8C(in which both the cover 200 and the vibrating member 180 are removed),the mechanism, which is generally indicated at 202, comprises a drivegear member 204, a driven gear member 206, and an operating cable 208having an enlarged end (not illustrated), for example having a generallyspherical shape with a cross-sectional diameter somewhat larger thanthat of the operating cable.

The drive gear member 204 is formed with a toothed side 210 and anon-toothed side 212, and a groove 214 below the toothed side 210terminating in a catch 216, for example having a chamber 218 sized so asto accommodate the enlarged end of the operating cable 208, and anopening 220 to the groove 214 which is large enough to accommodate theoperating cable therethrough, but small enough to block passage of itsenlarged end. The drive gear member 204 is in fixed disposition relativeto the bearing frame 138, for example mounted to a post 210 connected toor formed with the vibrating mechanism 180.

The driven gear member 206 is rigidly mounted to the seat frame 150, andmeshes with the toothed side of the 210 of the drive gear member 204.

The operating cable 208 is threaded through the bearing frame 138,exiting therefrom at an aperture 222, and wrapping around tensionmembers 224 a, 224 b, which are similarly fixed disposition relative tothe bearing frame 138. As illustrated in FIG. 8D, the other end of theoperating cable 208 is received within one of the pivot links 142, forexample within a round end of the bottom of the bearing frame 138, andis secured by a catch 226 which is rigidly connected to (e.g., formed aspart of) an element of the infant seat 130 which does not move with thebearing frame, such as the support member 132 or interconnecting bar134.

In operation, when the bearing frame 138 is raised or lowered withrespect to the support member 132, resulting in a change in first angleα between the support member and the bearing frame, the operating cable208 is pulled in a corresponding direction to rotate the drive gearmember 204, thereby rotating the driven gear member 206, and changingthe second angle β between the bearing frame and the seat frame 150 apredetermined amount, for example the same amount. Thus the infant seatmay be designed such that there is a fixed relationship between firstangle α and second angle β.

The elements of the mechanism may be designed such that the seat frame150, and thus the position of the infant, is always at a fixed anglerelative to the floor (such as fully reclined, sitting up), irrespectiveof the height of the seat frame, as determined by the position of thebearing frame. The infant seat 130 may be designed with a fixedpredetermined position of the seat frame 150, or such that the angle maybe adjusted, but remain in the adjusted position even when the bearingframe 138.

Those skilled in the art to which this invention pertains will readilyappreciate that numerous changes, variations and modifications can bemade without departing from the scope of the invention mutatis mutandis.
